Analysis of Heat Exchanger Process with Long Dead Time
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 7
Abstract
This paper presents the analysis of time delayed system controlled by a Proportional Integral controller and smith predictor to compensate the long dead time occurred in a process. For a test bed purpose a heat exchanger model is used. In order to generate modelling of shell and tube heat exchanger a Levenberg marquardt algorithm is used which trains artificial neural network 10 to 100 times faster than the usual back propagation algorithm. The generated first order plus dead model show the delayed time of -23.6 sec. Smith predictor is used to adjust the settling time more quickly as compare to Proportional integral controller and compensate the process. The generated result shows more effectiveness as compared to the previous result using MATLAB simulation software. Frequency analysis for the robustness is performed.
